Definitions

  • compositions which when diluted with water form stable emulsions suitable for application to plants to kill meristematic tissue without damaging mature tissue or subsequent'plant growth. (E.g., as chemical "pinching" agents for ornamental plants, trees and flowers.)
  • Such compositions are prepared at a central location and sold to the eventual user who prepares a more dilute aqueous emulsion. Accordingly it is desirable to have single phase compositions which are homogeneous on a molecular scale to ermit the eventual user to accurately measure the amount of material being used. It is also esthetically desirable to have a clear single phase composition.
  • compositions of this invention which are suitable for dilution with water to form emulsions for use as chemical pinching agents for plants consist essentially of: v
  • A a mixture of 1. methyl ester of straight chain saturated fatty acid containing from about six to about 12 carbon atoms and 2. fatty acid ester of polyethoxylated sorbitan wherein the fatty acid contains from about ten to about l8 carbon atoms and wherein there are from about five to about 80 ethoxy moieties per molecule; the ratio of said methyl esters to said fatty acid esters of polyethoxylated sorbitan being from about 3:1 to about 121.2; and A B. as a coupling agent to make said composition clear and single-phase, from about 4 percent to about 16 percent of water by weight of the total composition.
  • the gsource of the fatty acids used is not critical and can be either a inaturalsource such as coconut oil or a synthetic source.
  • the emulsifiers for the methyl esters in the aqueous emul- ISIOIIS (chemical pinching agents) formed from the concentrated compositions of this invention are fatty acid esters of polyethoxylated"sorbitan.
  • Suitable fatty acids useful in forming the esters of polyethoxylated sorbitan include: decanoic, undecanoic, dodecanoic, tridecanoic, tetradecanoic, pentadecanoic, hexadecanoic, heptadecanoic, octadecanoic, and octadecanoic acids or mixtures thereof.
  • ethoxy moieties per molecule are preferred for ease of formulation and efi'ectiveness of the diluted composition as hereinafter described as a chemical pinching agent.
  • Preferred emulsifiers which give the most stable emulsions for use as chemical pinching agents with minimum plant damage (phytotoxicity) are: dodecanoate ester of polyethoxylated sorbitan containing an average of about 20 ethoxy moieties per Qmolecule; oleate-ester of polyethoxylated sorbitan containing an average of about 20 ethoxy moieties per molecule; and Idodecanoate ester of polyethoxylatd sorbitan containing an gaverage of about five ethoxy moieties per molecule.
  • the most preferred emulsifier is the dodecanoate ester of polyethoxylated sorbitan containing an average of about 20 ethoxy moieties per molecule.
  • the preferred ratio of methyl ester to emulsifier is from about 2:1 to about 1:12 and the most preferred ratiois about 1:1. These ratios are preferred for maximum pinching at minimum phytotoxicity.
  • the preferred amount of water is from about 6 percent to about 12 percent by weight of the composition and the most preferred amount is about 10 percent by weight of the composition.
